A pilot study investigated the effects of Ginkgo biloba extract (EGb) on cerebral blood flow (CBF) in nine healthy elderly men, using dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSC-MRI). After four weeks of EGb supplementation (60 mg twice daily), results indicated a mild increase in CBF, particularly in the left parietal–occipital white matter, suggesting that EGb may enhance cerebral perfusion in specific brain regions.
